Cobalt nanoparticles synthesis from Co(CH3COO)2 by thermal decomposition

Size controlled synthesis of Co nanoparticles by combination of organic solvent and surfactant

“…For instance, thermolysis of Co 2 (CO) 8 has been successfully employed [30] to produce Co nanoparticles in a variety of polymeric matrices which played an important role in Co nanoparticles formation in controlling the size, shape and properties of the resultant nanoparticles. Shao et al [31] prepared Co nanoparticles using the non-toxic cobalt acetate as a precursor by thermal decomposition with the particle size controlled between 8 and 200 nm using various surfactant combinations of trioctylphosphine, oleylamine and oleic acid. Using the same method, Shukla et al [32] reported that the shapes of cobalt nanoparticles depended on the type of the surfactant used in the synthesis and the temperature at which the cobalt precursor was added to the reaction mixture.…”

Development of a microemulsion-based process for synthesis of cobalt (Co) and cobalt oxide (Co3O4) nanoparticles from submicrometer rods of cobalt oxalate

“…Monodisperse and uniform cobalt nanocrystals (6-8 nm) were synthesized earlier by the reduction of cobalt(II)bis(2-ethylhexyl)sulfosuccinate (Co(AOT) 2 ) using NaBH 4 as the reducing agent [29]. Another report notes a broad distribution nm) of cobalt nanoparticles [30] obtained by the thermal decomposition of cobalt acetate tetrahydrate.…”

Sacrificial seed mediated synthesis of copper nanopots by a modified polyol process

“…Very low M s value could be explained due to the fact that Co is only a minor constituent, with 1.8 wt% contribution to the total mass; if back calculation is done, it would turn out a higher M s value of 111 emu g for 100 wt% Co. Even this value is lower when compared to 168 emu g for bulk Co, but it is comparable to those reported for Co NPs [27]. Higher coercivity value could be attributed to the possible Cu covering over Co [28].…”
